Hepatoprotective Activities of Colocasia esculenta (L.) Schottin Mice Model with Liver Injury Induced by Paracetamol

This paper uses the model of experimental mouse liver damage with paracetamol to evaluate the liver protective effects of the methanol extract (Colocasia esculenta (L.) Schott) (MCE). After 8 days, the hepatoprotective activities of MCE in mice (damaged by paracetamol) at doses of 500, 1,000 and 2,000 mg/kg/day proved effective as the AST enzyme content decreased by 6.98, 22.84 and 26.59%, respectively; and ALT decreased by 53.17, 56.46 and 57.93%, respectively. MCE at a dose of 1,000 mg/kg/day had a protective effect equivalent to that of silymarin (used in liver treatment) at a dose of 50 mg/kg/day and MCE at a dose of 2,000 mg/kg/day had better effect. Observation of the microscopic liver tissue cross section also revealed that the mice treated with MCE of C. esculenta at doses of 1,000 and 2,000 mg/kg/day showed significantly improvement in their liver tissues compared to the non-treated control group.
